中文提要

应急预案又称应急计划,是针对可能的重大事故(件)或灾害,为保证迅速、有序、有效地开展应急与救援行动、降低事故损失而预先制定的有关计划或方案。我们很难掌握突发性事件的发生,但是可以通过完整的预案体系来将其损失降低到最低程度。“基于GIS的世博园突发事件应急预案系统”是北京市劳动保护科学研究所的“安全社区”项目中的子项目,安全社区是我国城市发展中的一个热点问题,对实现公共安全建设有着重要的实际意义。随着奥运脚步的临近,安全问题也被越来越多的人所关注。

目前我国在这方面尽管有很多的机构在做研究,但还没有完全成熟的应用系统问世,所以该课题的研究工作具有相当的应用前景和实用价值。本系统通过VB的开发平台,结合了MapInfo的地理信息功能,能够实现GIS的信息检索、地图定位、空间查询、地图热链接等功能。

本文的取得的主要成果有:开发平台的链接;定位搜索、空间数据查询;地图热链接;设立了事故记录功能。基本能够完成应急预案中的操作要求。

Abstract

The Emergency case,also called the contingency plan, aims at the possible significant accidents, develops effectively emergency with the rescue motion, and reduces the accident loss .We are very difficult to grasp the occurrence of the burst characteristics event, but we can reduce its loss to the lowest degree through the integrity predetermined plan system. \on GIS event emergency predetermined plan and retrieval system” is the sub- project of Beijing labor protection research institute \security community”. The security community is a hot problem in urban development of our country, and has important and actual significance for realizing common security construction. With Olympic Games is closing, the safe problems are also paid more attention to by more and more people.

At present, there does not have the completely mature application system in this aspect to be published in domestic, though many big development facilities already started the system-related development work in our country, so the research in this topic had a suitable application prospect and a practical value. This system can realize such functions as GIS information retrieval, map fixation, spatial inquiry, map hot link through the VB development platform and unifying the MapInfo geography information function,.

This article obtains the main achievements including: the link of the development platform; Localization search, space data inquiry; Map hotlink; the establishment of accident records. It meets basically the operation requirement in the emergency predetermined plan.

Key words:GIS,MapInfo,Emergency case,Urgent event
